Abstract (en)
The invention refers to hard coating coated parts which are coated with a hard coating containing the elements Al, Ti, Cr, N, O with a chemical composition of each element of AlaTibCrcNwO100-w in the range of 30≤a≤70, 30≤b≤70, 0.5≤c≤20 a+b+c=100 at % and 70≤w≤99 %. The invention aims at a superior adhesion between the coating and the substrate without a reduction of the wear resistance, of the oxidation resistance and the friction properties, but improving every one of the coating properties to achieve a stable behavior under heavy-duty cutting resulting in a long life-time. Therefore, it is proposed that the full width at half maximum (FWHM) 2θ of the (200)x-ray diffraction peak is larger than 0.4 DEG and smaller than 0.7 DEG .
